I took pictures during my last build, so I thought I'd post them up in case they'd be a good reference.

Here's a compilation of the pinouts for various DJI NAZA peripherals. Hopefully it'll be a useful reference for tweakers and modders out there, and will save you the trouble of shaving injection molded plastic connectors. But it's always a good idea to verify pin-outs with a multimeter!

Some of the pictures are from the top of the connector, some are from the bottom. Apologies for the inconsistency, but I've tried to note it in each case.

BTU: THIS ONE IS DIFFERENT

This cable throws you for a loop. You notice that there is a GREEN cable rather than orange on the BTU side. But on the NAZA side, it's the standard red/brown/yellow/orange cable. You have to strip a little more away to get a better picture:

At the BTU side, the GREEN wire is actually YELLOW. And the YELLOW is actually ORANGE. I know, right? Lesson: Always double check cable continuity, either by stripping away the wire sheath or using a multimeter. Anyways, the pinout is as follows:

BTU (left to right): Brown, orange, yellow, red (GND, CH, CL, V+)

CANBus cable: as before, with clasp facing up, left to right it will always be: Yellow, orange, brown, red (CL, CH, GND, V+). Note picture is from the bottom.
